Perhaps you should try some spelling variations:
"qoe estimation algorithms" » "qoe estimation algorithm", "qoe optimization algorithms", "qoe optimisation algorithm", "pose estimation algorithms", "_ estimation algorithms", "cover estimations algorithms"
"one optimized algorithm" » "one optimized algorithms", "one optimizer algorithms", "_ optimized algorithm"
"dong optimized algorithm" » "dong optimized algorithms", "dong optimizer algorithms", "cong optimized algorithm", "dung optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("one optimized algorithm") OR ("dong optimized algorithm"))) OR ("qoe estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"one optimized algorithm\") OR (\"dong optimized algorithm\"))) OR (\"qoe estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( one optimized algorithm ) OR ( dong optimized algorithm ))) OR ( qoe estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("one optimized algorithm") OR ("dong optimized algorithm"))) OR ("qoe estimation algorithms"))*.
